 Minimal reproducer of the regression:

   $ cat foo.bash

   declare -A hash
   echo ${hash[a/b]}
   echo $?

   $ /bin/bash foo.bash
   4.2.45(1)-release

   $ ~/bleeding/bin/bash foo.bash
   4.3.0(1)-alpha
   foo.bash: line 3: a/b: division by 0 (error token is b)
   1

 Notice that the new behaviour breaks the gnulib-tool script
 (that's how I noticed this regression).
 
 You're just not bleeding-edge enough. :-)
 
 That problem was fixed several weeks ago as part of the ongoing cleanup
 of `invisible placeholder' variables (variables with attributes but no
 values, which are technically unset).

Indeed, I had forgotten to git pull. Everything seems to work fine with
the latest 'devel' branch.

Thanks, and sorry for the noise,
